A woman was left "shaken" after a large wad of cash was stolen from her at a bank in Wembley.
The victim had been waiting to deposit £6,000 at a bank on the High Road at 11.15am on Saturday, January 28.
But she was left horrified after a man accosted her, snatched the envelope with the cash inside and fled the scene.
The woman, aged in her 60s, said she is nervous going out in public and rarely carries a purse following the horror incident.
She said: "This theft has affected me deeply; first of all I took out a loan of £6,000 to give back to my partner. He did not ask but to do this but I would feel guilty for the rest of my life if I didn't give him something back, knowing how hard he works and planning for our future. I am now in debt for the next five years.
"This also affected me that now I am a nervous person walking on the street, I don't like anyone coming too close to me, and I hardly take a handbag with me when I am leaving home anymore.
"It was my partner's money, I was going to put it back in the bank on his behalf because he works mostly six days a week and couldn't catch the bank. He withdrew the money to do some business but it didn't work out as planned. This business was to help us retire a little earlier."
PC Joss Stott, from the North West Command Unit, said: "We are renewing this appeal in the hope that someone recognises the man in this image - if you do, please contact police immediately.
"While the victim was not physically harmed, she is understandably shaken and upset by this brazen theft. I would urge anyone who can help identify this person or can assist the investigation to get in touch."
There have been no arrests and enquiries continue.
